2 SHEETS-SHEET 1'.

At each end of the slag pan there is a pair of links 11 and 12'whose lower ends are suitably pivoted to the ends of the doors 7 and whose upper ends are pivoted to or nk arms, the upper end of each link 11 being pivoted to a crank arm .13, and the upper end of each link 12 being pivoted to a crank arm 14. At one end of the pan said crank arms 13 and 14 are connected to bell crank levers 15 and 16, which bell cranks are fast on horizontal parallel longitudinal shafts 17 and 18, while at the other end of the pan the crank arms 13 and 14 are preferably only single crank arms made fast on these shafts 17 and 18, as shown in Fig. 4.- The bell crank levers 15 ahd 16, therefore, not only have the arms 13 and 14 which are pivoted to the links 11 and 12, but also they have the crank arms 19 and 20. At one end of the pan, therefore, thereare these bell crank'levers havin members 19 and 20 projecting toward 'eac other. A link 21 connects the lower end of arm 19 with the upper end of arm 14, as shown in Fig. 1, being pivoted to both of said arms. Also to the end of arm 20 is pivoted a link 22 whose opposite end is pivoted to an arm 23 of a bell crank lever having an operating handle 24, said bell crank lever being P1V' oted at 25 in a bracket 26 attached to some convenient part 27 .of the locomotive frame, the lever handle 24 serving as the dump lever handle to open the doors 7.

The two links 11 and 12 while occupying a generally vertical position. are inclined outwardly and are bent or curved so that their upper ends are carried considerably beyond the outer faces of the sides 4 of pan 3. This arrangement makes the leverage self-locking, sincethe upper ends-of links 11 and 12 which are pivoted to the arms 13 and 14 at the opposite ends of the pan are past the line which might be drawn through the centers of the pivots of hell crank levers 15 and 16 and the pivots at the lower ends of links 11' and 12 as shown by the dotted lines a, a, in F i I 1. Furthermore it will be perceived that in view of the fact that the lever 24 is pivoted at 25, and that the said lever arm 24 is much longer and consequently considerably heavier than arm 23, said lever 24 is able by its own weight to keep the link 22 in compression and thus prevent or counteract any effect that the vibration of the locomotive or the running of the train might have to cause the doors or leaves '7, 7 to fly open and prematurely discharge the contents.

An additional safety device consists of a steel safety pin 28 whichis inserted in the dump lever bracket 26 at a point close to the dump lever 24, as shown in Fig. 1, and when in placeit is impossible to lift the lever 24. for the purpose of operatin the pan to discharge its contents. It wi noted also that the links 11 and 12 of which there are two adjacent to each end 3 are prevented from going past their centers of operation any farther than is desirable by reason of the fact that they come in con tactwith and rest upon the hubs of the bell crank levers 15 and 16. 15 and 16 have their members separated for this purpose so as to occupy different but parallel planes, and between the arms of each bell crank there is a hub, as shown. Ordinarily the pan will beduinped by removing the safety pin 28 and lifting the lever 24, the result of which through the connection of arm 23 with link 22 will be to draw on said link 22 and thereby vibrate Said bell cranks the bell crank 16, which, being connected.

with the bell crank 15 by the link 21, im-

parts a simultaneous vibration to bellcrank- 15 so that the two bell cranks 15 and 16 oscillate simultaneously and communicate motion to the links 11 and 12 which are pivoted to said bell cranks and thus open the doors or leaves 7, and as said bell cranks 15 and 16 are fast on the shafts 17 and 18 at one end of the pan, motion is communicated to the other end of the pan through these shafts 17 and 18 so that the arms,13

and 14 at said end of the pan are operated at the same time, and the links 11 and 12 at that end partake of the same movement as the first-named pair of links, it being evident, therefore, that at both ends of the pan the curved links 11 and 12 operate in the same way and produce similar effects upon the leaves 7, 7. ment of" the dump lever handle 24 will restore the parts to the. former position and close up the doors or leaves 7 and place the pan in the same condition that it was before .it was discharged.

Although the .pan is ordinarily dumped by the operator when he is standing on the ground outside of the frame or at some other point, yet it must be evident under many conditions it may be preferable to operate the dumping mechanism from the engineers cab, and in order to provide means for this with ease and convenience, Iextend one. of the longitudinal shafts ,on which the bell cranks 15 and 16 and the crank arms age mounted, that is to say, one or the other of the shafts 17 or 18 (in. the particular example illustrated it is the shaft 18) back to some point beneath the cab say, or to some point where it is connected to other shafts or levers so that the dumping operation may be accomplished from the distant point, that is to say, from a point within the cab.

Obviously many changes may be made in the precise construction and arrangement of the various parts of my improved sla pan bviously a reverse move,
